I/O capacity is a complex function of the number of requests and the size of the requests (number of KB transferred) so it's hard to come up with a reliable "Total Available" capacity figure.

Also, the apparent logical I/O capacity for the file system can be much higher than physical I/O capacity for the disk subsystem, thanks to cache and cylinder reads.
